More specifically, in embodiments in which MR 104 is affiliated with two or more talkgroups on the infrastructure network via the first wireless communication interface 206, the MR 104 may authenticate only with those MRs via the second (short-range) wireless communication interface 208 in accordance with a current channel selection input of the radio.

  • FIG. 4 depicts a ladder diagram 400 illustrating processing steps, message transmissions, and message receptions in a communication system, including MR 104, MRs 110, BS 102, and controller device 116 of FIG. 1 , for selectively routing group communications amongst multiple networks in accordance with at least one embodiment. While FIG. 4 is described as a separate and distinct embodiment from that set forth in FIG. 3 , in some embodiments, FIG. 4 may illustrate processing steps, message transmissions, and message receptions logically following those set forth in FIG. 3 in situations in which the infrastructure RAN is still accessible. In other words, in situations in which MR 104 of FIG.
  • FIG. 3 has access to talkgroups on multiple networks, such as a talkgroup on an infrastructure network via BS 102 and a sub-talkgroup created via authenticated links with one or more MRs 110, the processes described and set forth in FIG. 4 may be used to select which of the talkgroups and networks to transmit communication media to.

  • MR 104 detects and/or otherwise couples with, forms, or affiliates to a first talkgroup on a first wireless communication network via a first wireless communication interface 206 and unidirectional or bidirectional message transmissions 402, and detects and/or otherwise couples with, forms, or affiliates to a sub-talkgroup of the first talkgroup on a second wireless communication network via a second wireless communication interface 208 and unidirectional or bidirectional message transmissions 404.
  • FIG. 4 and consistent with the examples set forth in FIG.
  • the first talkgroup is an infrastructure talkgroup established via an infrastructure network (including BS 102 and controller device 116), while the sub-talkgroup is an ad-hoc talkgroup having a subset of MR members of the first talkgroup and that is established via an ad-hoc network.
  • the roles of talkgroup and sub-talkgroup may be reversed such that the talkgroup is established via the ad-hoc network and the sub-talkgroup established via the infrastructure network, and in still further embodiments, the talkgroup and sub-talkgroup may both be established via separate infrastructure networks (and wireless network interfaces 206, 208) or via separate ad-hoc networks (and ad-hoc network interfaces 206, 208). Still further, entirely separate talkgroups may be established via infrastructure and/or ad-hoc networks that are not related by talkgroup and sub-talkgroup.
  • MR 104 detects a request to transmit group communication media including one or more of voice, audio, image, or video data to members of a first or second talkgroup.
  • the first talkgroup may be determined as a function of a channel selection input and the second talkgroup may be a sub-talkgroup of locally authenticated MRs of the first talkgroup.
  • the first talkgroup and the second talkgroup may be a separate pair of talkgroups determined as a function of a channel selection input or some other input at MR 104.
  • communication media is transmitted to a selected talkgroup via one of a first and second wireless communication interface as a function of a state of a channel selection input, while communication media transmitted via the other of the first and second wireless communication interface is broadcast or otherwise transmitted to all MRs directly accessible to the MR 104 via that interface or to a union of multiple talkgroup MRs or sub-talkgroup MRs accessible to the MR 104 via that interface.
  • Detecting the request to transmit may include detecting activation of a PTT key 211, reception of voice without detected activation of the PTT key 211, recognition of a corresponding voice command, the selection of a piece of stored or captured media (image, video, etc.) to transmit via user interface 210, or some other detected input or condition. Other possibilities exist as well.
  • the MR 104 selects one of a first talkgroup via the first wireless communication network and a second talkgroup via the second wireless communication network as a target talkgroup to transmit the communication media to, and does so as a function of a determined state of the PTT key 211.
  • the MR 104 determines that the PTT key 211 is activated, the MR 104 will select one of the first talkgroup via the first wireless communication network and the second talkgroup via the second wireless communication network as a target talkgroup to transmit the communication media to, and if the MR 104 determines that the PTT key 211 is de-activated, the MR 104 will select the other of the first talkgroup via the first wireless communication network and the second talkgroup via the second wireless communication network as the target wireless network to transmit the communication media to.
  • the state of the PTT key 211 may be detected in any number of known ways, including accessing a memory location that stores a state of a variable associated with the PTT key 211 input status, reading a state of a switch circuit, reading a state of a presence detection circuit, or any one or more other mechanisms for determining an activated or de-activated state of a binary input.
  • an activated PTT key 211 is configured at MR 104 to be associated with a desire to transmit the communication media to a talkgroup via the first (infrastructure) wireless interface and infrastructure network, while a de-activated PTT key 211 is configured at MR 104 to be associated with a desire to transmit the communication media to a sub-talkgroup via the second (short-range) wireless interface and ad-hoc network.
  • This configuration allows audio, video, and/or images captured at the MR 104 (e.g., audio captured via an always-activated microphone portion of its user interface and digitally encoded or images captured via an always-activated imaging sensor portion of its user interface and digitally encoded, etc.) to be automatically and substantially instantaneously provided to all sub-talkgroup members within a vicinity of the MR 104 and may aid the MR 104's user in accomplishing a location-specific task in the area, while communication media determined important enough by MR 104's user to warrant further distribution to the entire talkgroup with which it is currently associated via the infrastructure network to be transmitted there (and only there, or to both talkgroup and sub-talkgroup) when the user activates the PTT key 211.
  • audio, video, and/or images captured at the MR 104 e.g., audio captured via an always-activated microphone portion of its user interface and digitally encoded or images captured via an always-activated imaging sensor portion of its user interface and digitally encoded, etc.
  • communication media could instead be routed to the infrastructure wireless network when the PTT key 211 is de-activated and to the ad-hoc wireless network when the PTT key 211 is activated.

  • a subTG_comm_media_xmit 410 message including the communication media as illustrated in FIG. 4 .
  • additional messages may be transmitted based on a size of the communication media to be transmitted.

  • the subTG_comm_media_xmit 410 message may not identify the target recipient or recipients, but only those MRs 110 that have authenticated MR 104 receive, decode, and playback the media included in the subTG_comm_media_xmit 410 message.
  • one or more of the MRs 110 transmits communication media in return to MR 104 in one or more subTG_comm_media_rcv 412 messages.
  • MR 104 receives the subTG_comm_media_rcv 412 message and uses similar mechanisms to determine whether it is an intended target of the subTG_comm_media_rcv 412 message and whether to decode and playback media contained in the message.
  • subTG_comm_media_rcv message 412 identifies the MR 104 as a target of the message, identifies a talkgroup with which MR 104 is affiliated as a target of the message, and/or MR 104 determines that the subTG_comm_media_rcv 412 message was transmitted by a MR 110 that MR 104 has already successfully authenticated, it decodes and plays back the received media, perhaps via a speaker and/or display portion of its user interface 210.
  • MR 104 detects a new request to transmit new group communication media to members of a currently selected talkgroup or sub-talkgroup(s). This time, the MR 104 determines that the PTT key 211 is activated and that the new communication media is to be transmitted via its first (infrastructure) communication interface 206 to MR members of the talkgroup on the first infrastructure network, and then actually transmits a TG_comm_media_xmit 414 message including the new communication media to the infrastructure via BS 102 and controller device 116 for further distribution to talkgroup members, as illustrated in FIG. 4 . Although only one TG_comm_media_xmit 414 message is illustrated in FIG.
  • additional messages may be transmitted based on a size of the new communication media to be transmitted.

  • MR 104 receives the TG_comm_media_rcv 414 message and uses similar mechanisms to determine whether it is an intended target of the TG_comm_media_rcv 414 message and whether to decode and playback the further communication media contained in the message.
  • TG_comm_media_rcv message 414 identifies the MR 104 as a target of the message or identifies a talkgroup with which MR 104 is affiliated as a target of the message, it decodes and plays back the received further communication media, perhaps via a speaker and/or display portion of its user interface 210.
  • the MR 104 may at step 422 either playback one first while temporarily buffering the other for later playback, or may attempt to mix the communication media together and present them simultaneously to the user.
  • the MR 104 may mix the audio, via processor 202 or a separate digital signal processor circuit, and play back the mixed audio to the user via a speaker portion of the user interface 210.
  • one audio or voice stream may have its gain amplified relative to the other, perhaps based on assigned priorities of talkgroup versus sub-talkgroup or assigned priorities of network interfaces, etc.
  • the communication media received from the talkgroup or over the infrastructure network may have its signal gain relatively increased (e.g., amplified) or the communication media received from the sub-talkgroup or over the ad-hoc network may have its signal gain relatively decreased (e.g., attenuated) prior to summing the two audio or voice streams together and playing back the audio via a speaker portion of the user interface 210.
  • the MR 104 may buffer the received communication media until the transmission of TG_comm_media_xmit_3 422 is completed, or may play back the communication media included in the subTG_comm_media_rcv_3 424 message while transmitting the TG_comm_media_xmit_3 422 message.
